Bowman-Birk inhibitor is a protease inhibitor derived from soybeans that has demonstrated chemopreventive activity in a number of in vitro and animal systems. We conducted a 1-month phase IIa clinical trial of Bowman-Birk inhibitor concentrate (BBIC) in patients with oral leukoplakia. BBIC was
The protease catalyzing the hydrolysis of the tripeptide fluorescence substrate, butoxycarbonyl-valine-proline-arginine-(7-amino-4-methylcoumarin) (Boc-Val-Pro-Arg-MCA) and the neu oncogenic protein are potentially useful biomarkers for human cancer prevention studies. In the present study, we
The Bowman-Birk inhibitor (BBI) is a soybean-derived serine protease inhibitor and a potential cancer chemopreventive agent for humans. In this Phase I clinical trial, BBI concentrate was administered as a single oral dose to 24 subjects with oral leukoplakia. Pharmacokinetics of BBI was analyzed,
The epithelial cells in squamous carcinoma and leukoplakia of the oral cavity possess the cell surface protease, guanidinobenzoatase (GB), in an active form. GB is closely similar to plasminogen activator, a protease associated with both transformed cells and tumour cells. The active centre of GB
Oral premalignancy serves as an ideal model for study of chemopreventive agents. Although 13-cis-retinoic acid showed reversal of oral premalignancy, toxicity, and reversal of clinical response after cessation of therapy obviated its widespread use. A search for nontoxic agents with cancer
The objective of this work was to assess the prevalence of human immunodeficiency virus-related oral lesions (HIV-ROL) in HIV-positive/acquired immunodeficiency syndrome (AIDS) patients receiving highly active antiretroviral therapy (HAART) including HIV-protease inhibitors. One hundred fifty-five
Available treatments for multiple sclerosis (MS) require frequent injections and have significant side effects. Proteases generated during inflammation are involved in the induction of tissue damage during inflammatory demyelination in the central nervous system (CNS). The Bowman-Birk Inhibitor
OBJECTIVE
The purpose of this study was to determine temporal trends in the prevalence of oral manifestations of human immunodeficiency virus (HIV).
METHODS
Five hundred seventy HIV-infected adults recruited consecutively were examined by using established presumptive clinical criteria for
BACKGROUND
The incidence of oral lesions related to human immunodeficiency virus (HIV) infection have been investigated after treatment with highly active antiretroviral therapy (HAART) including protease inhibitors (PI) but no data are available on the effect of non-nucleoside reverse transcriptase
BACKGROUND
The advent of new antiretroviral drugs such as protease inhibitors (PI) has generated sensible changes in oral manifestation patterns in human immunodeficiency virus (HIV) infected adult patients.
OBJECTIVE
The purpose of the present study was to assess whether the use of highly active
Drug abuse is a serious problem associated with different pathological outcomes including modulating the immune system. Drug abuse is rising in Saudi Arabia and so as TB, a disease of worldwide significance, caused by immunological modulation in the host system. Khat chewing is a common practice in
Chemopreventive agents are natural or synthetic agents administered to prevent, inhibit or reverse one or more of the stages of carcinogenesis. Natural agents include vitamins, coumarin, indoles, flavones, plant sterols and selenium salts. Synthetic agents include retinoids, phenolic antioxidants,
Chemoprevention, defined as the use of natural, synthetic, or biologic compounds to halt, reverse, or prevent the initial phases of carcinogenesis or the progression of neoplastic cells to cancer, has produced successes, but progress has been slow. Notably, in the field of oral cancer prevention and
Oral lesions (OL) have an important prognostic value for HIV/AIDS patients. However, the behavior of OL in HIV/AIDS patients undergoing highly active antiretroviral therapy including efavirenz (HAART/EFV) has not been documented. Our objective was to establish the prevalence of OL in HIV/AIDS
Leukoplakia in the oral cavity has been used as a putative surrogate marker of head and neck cancer development. A class of chemoprevention compounds, called protease inhibitors, has been shown in vitro and in animal models to effectively suppress premalignant lesions. Bowman-Birk inhibitor (BBI) is
